  During normal use, the door trim needs to have a certain degree of rigidity. However, if the simple rigidity of the door trim is increased, the door trim will not easily be deformed in the secondary collision of the occupant in the side collision of the vehicle (hereinafter referred to as “side collision”). There is room for improvement in reducing the collision reaction force.

  The present invention has been made in view of the above circumstances, and has an automotive door trim mounting structure capable of ensuring the rigidity of a door trim and reducing a collision reaction force due to a secondary collision of an occupant in a side collision. The purpose is to provide.

  In order to solve the above-described problem, an automobile door trim mounting structure according to claim 1 is attached to a vehicle interior side of a door inner panel constituting a door inner plate of a side door and has an outer trim member having an opening. An inner trim member that covers the opening of the outer trim member and is attached to the outer trim member in a state where a gap is provided between the outer trim member and the outer trim member. At the attachment portion of the inner trim member and the outer trim located in the vehicle rear region of the door trim, the front trim is inserted into a locking hole formed in the inner trim member and formed in the outer trim member and elastically deformed. A locking piece whose portion is locked to the peripheral portion of the locking hole, and a small amount of the locking piece of the inner trim member on the vehicle upper side and vehicle lower side. A mounting boss that is provided in at least one of the holes and is inserted into an insertion hole formed in the outer trim member and is fixed in a state of being prevented from being detached from the outer trim member, Yes.

  In the mounting structure of the automobile door trim according to the first aspect, the outer trim member constituting a part of the door trim is attached to the vehicle interior side of the door inner panel constituting the door inner plate of the side door. An inner trim member constituting a part of the door trim is attached to the outer trim in a state where a gap is provided in the vehicle width direction between the outer trim member and the outer trim member. The outer trim member has an opening, and the opening is covered with the inner trim member.

  And in the attachment part of the inner trim member and outer trim member located in the vehicle rear region in the door trim, the inner trim member is provided with a locking piece, and the outer trim member is inserted with the locking piece. A hole is formed. After the locking piece is inserted into the locking hole, the tip of the locking piece is locked to the peripheral portion of the locking hole in a state where the locking piece is elastically deformed. That is, a pressing force is applied to press the inner trim member toward the outer trim member (outward in the vehicle width direction) via the locking piece. For this reason, a reaction force against the pressing force is generated in the inner trim member, and the inner trim member can secure a necessary rigidity in this portion.

  On the other hand, the inner trim member is provided with a mounting boss on at least one of the locking piece on the vehicle upper side and the vehicle lower side, and the mounting boss is inserted into the insertion hole formed in the outer trim member. The boss is fixed in a state where it is prevented from coming off from the outer trim member. In this state, a gap provided between the inner trim member and the outer trim member is filled with the mounting boss. Thereby, an inner side trim member can be firmly attached to an outer side trim member via an attachment boss | hub. That is, the mounting boss is stretched between the inner trim member and the outer trim member, and the inner trim member is difficult to bend.

  As described above, during normal use of the door trim, the locking piece that is locked to the periphery of the locking hole in an elastically deformed state and the mounting boss that is fixed to the outer trim member in a locked state. The rigidity is ensured.

  Here, the locking piece is elastically deformed, and its tip end is locked to the periphery of the locking hole so as to stretch between the inner trim member and the outer trim member. Absent. For this reason, when the inner trim member is deformed to the outer trim member side due to a secondary collision with the occupant's door trim during a side collision of the automobile, the tip of the locking piece comes off from the peripheral portion of the locking hole, and the inside of the locking hole The locking piece moves from the tip side to the root side.

  As described above, since the locking piece is elastically deformed and the tip of the locking piece is only locked to the periphery of the locking hole, the tip of the locking piece is around the locking hole. When the state of being locked to the portion is released (when the tip of the locking piece is removed from the peripheral portion of the locking hole), the reaction force generated by the locking piece is reduced. That is, it is possible to reduce the collision reaction force due to the secondary collision of the occupant in the side collision, and to ensure the side collision performance related to the secondary collision of the occupant.

  According to a second aspect of the present invention, there is provided the mounting structure for an automobile door trim according to the first aspect, wherein the locking piece is in contact with an inner edge portion of the locking hole.

  When the inner trim member is deformed to the outer trim member side due to a secondary collision with the occupant's door trim at the time of a side collision, the locking piece moves in the locking hole from the distal end side to the root side of the locking piece. For this reason, in the configuration of the second aspect, the locking piece is provided in contact with (interfering with) the inner edge portion of the locking hole, so that the locking piece is moved between the locking hole and the locking hole when the locking piece is moved. Causes a sliding resistance, which absorbs impact energy.

  According to a third aspect of the present invention, in the vehicle door trim mounting structure according to the second aspect, the locking piece extends from the inner trim member toward the outer edge side of the inner trim member and extends in the vehicle width direction. A locking piece main body extending in a direction inclined with respect to a straight line, and provided at a distal end portion of the locking piece main body, folded back toward the inner trim member side and locked to a peripheral portion of the locking hole. And a locking claw.

  In the structure of Claim 3, the locking piece is comprised including the locking piece main body and the locking claw. The locking piece main body extends from the inner trim member toward the outer edge side of the inner trim member and extends in a direction inclined with respect to a straight line along the vehicle width direction. A locking claw is formed at the tip. The locking claws are folded back toward the inner trim member and are inserted into locking holes formed in the outer trim member. And the latching claw is latched by the peripheral part of a latching hole in the state which the latching piece main body was inserted in the said latching hole.

  At the time of a side collision, when the inner trim member is deformed to the outer trim member side due to a secondary collision with the occupant's door trim, the locking main body moves in the locking hole from the tip side to the root side. That is, the locking piece moves to the outer trim member side. Compared to the case where the locking piece main body is formed along the straight line along the vehicle width direction, the locking piece main body is inclined with respect to the straight line along the vehicle width direction. A piece body can be formed long. Thereby, the length which a sliding resistance produces between a locking piece main body and a locking hole can be lengthened. That is, the stroke in which the impact energy is absorbed can be lengthened.

  According to a fourth aspect of the present invention, there is provided the automobile door trim mounting structure according to any one of the first to third aspects, wherein a clip that is fitted to the door inner panel by press fitting is provided on the outer trim member. The stop piece is provided on the vehicle front side of the clip.

  According to the fourth aspect of the present invention, the outer trim member is provided with a clip and is fitted to the door inner panel by press fitting. A locking piece is provided on the vehicle front side of the clip.

  Since the clip is attached to the door inner panel by press fitting, the outer trim member side needs to be rigid enough to withstand the pressing force for attaching the clip to the door inner panel. For this reason, in the part in which the said clip is provided, it sets so that rigidity may become larger previously than the other part in an outer side trim member. On the other hand, the portion where the locking piece is provided has lower rigidity than the portion where the mounting boss is provided. Therefore, by providing the locking piece on the vehicle front side of the clip, the rigidity of the mounting portion between the inner trim member and the outer trim is lower than the portion where the mounting boss is provided by the locking piece. The minutes can be secured by the rigidity of the clip.

  As described above, the automotive door trim mounting structure according to the first aspect of the invention can secure the rigidity of the door trim and reduce the collision reaction force due to the secondary collision of the occupant in the side collision. Has an excellent effect.

  The automobile door trim mounting structure according to the second aspect of the present invention has an excellent effect that the impact received by the occupant from the inner trim member at the time of a side collision can be reduced.

  On the other hand, the inner trim member 20 can be attached to the periphery of the opening 28 formed in the outer trim member 18, and the inner trim member 20 is attached to the outer trim member 18 as shown in FIG. In this state, the opening 28 is closed by the inner trim member 20.

  A door armrest 21 is provided substantially along the vehicle front-rear direction on the center side of the inner trim member 20 in the vehicle vertical direction. A side glass (not shown) provided on the side door 12 is provided on the upper surface of the door armrest 21. ) And the like are provided.

  As shown in FIG. 3, the inner trim member 20 has a substantially box shape, and a vertical wall 20 </ b> A is provided on the outer edge of the inner trim member 20. That is, the inner trim member 20 protrudes to the inside of the passenger compartment 22, and the front wall 20 </ b> B of the inner trim member 20 and the front wall 18 </ b> B of the outer trim member 18 in a state where the inner trim member 20 is attached to the outer trim member 18. A gap 38 in the vehicle width direction is provided between the two. Here, the shape of the vertical wall 20A is simplified and shown as a substantially straight line.

  Here, as shown in FIG. 1, on the outer edge side of the inner trim member 20, the mounting boss 40 corresponds to the insertion hole 34 and the locking hole 36 provided in the mounting seat surface 32 of the outer trim member 18. And the locking piece 42 is provided, respectively. That is, here, the mounting bosses 40 are provided on the vehicle front side and the vehicle rear side of the locking piece 42 or on the vehicle upper side and the vehicle lower side of the locking piece 42. The mounting boss 40 and the locking piece 42 are shown only on the vehicle rear side of the inner trim member 20 which is the gist of the present case.

  As shown in FIGS. 2 and 3, the mounting boss 40 has a cylindrical shape and is set to a size that can be inserted into the insertion hole 34 formed in the outer trim member 18. Further, substantially rectangular ribs 44 project from the outer peripheral surface of the mounting boss 40 in a cross shape along the vehicle longitudinal direction and the vehicle vertical direction. When the rib 44 is close to the vertical wall 20A of the inner trim member 20, the rib 44 is formed integrally with the vertical wall 20A. Further, the rib 44 is formed on a ridge line P (see FIG. 2) formed between the front wall 20B and the vertical wall 20A of the inner trim member 20 in the “substantially vehicle front-rear direction” and “substantially vehicle vertical direction”. The rib 44 may be inclined with respect to a straight line along the vehicle longitudinal direction or the vehicle vertical direction depending on the ridgeline P.

  Further, the rib 44 is set to be lower than the mounting boss 40, and the distal end portion of the mounting boss 40 can penetrate the insertion hole 34. Then, in a state where the distal end portion of the mounting boss 40 is inserted into the insertion hole 34, the distal end portion of the mounting boss 40 is exposed from the back side (the vehicle outer side) of the mounting seat surface 32, and the distal end surface of the rib 44 is the mounting seat surface. The movement of the mounting boss 40 (inner trim member 20) is restricted in a state where it abuts against the surface side of 32 (the vehicle inner side). At this time, the vertical wall 20 </ b> A of the inner trim member 20 contacts the front wall 18 </ b> B of the outer trim member 18.

  In this manner, with the movement of the mounting boss 40 restricted, as shown in FIG. 3, the tip of the mounting boss 40 is in a state of being crimped by heat (in a state where it is prevented from being detached by the melting portion 46). Fixed. Thereby, the inner trim member 20 is attached to the outer trim member 18 via the attachment boss 40.

  On the other hand, as shown in FIG. 4A, the locking piece 42 extends from the rear surface side of the front wall 20B of the inner trim member 20 to the vehicle width direction outer side and the vehicle rear side (the outer edge side of the inner trim member 20). The locking piece main body 48 extends in a slanted manner with respect to a straight line along the vehicle width direction. The locking piece main body 48 is set to a length that protrudes from the front end portion of the vertical wall 20A, and the front end portion of the locking piece main body 48 is substantially inward in the vehicle width direction and toward the vehicle rear side in a side view. A locking claw 50 that is folded back in a V shape is formed.

  The locking piece 42 can be inserted into a locking hole 36 formed in the outer trim member 18. The dimension W1 on the short side of the locking hole 36 is set to be smaller than the shortest distance (dimension W2) from the distal end portion of the locking claw 50 to the locking piece body 48. For this reason, when the locking claw 50 is inserted into the locking hole 36, the front end portion 50A of the locking claw 50 is elastically deformed toward the locking piece body 48 side (the opening of the locking claw 50). In a state where the angle is closed), it passes through the locking hole 36.

  In a state where the inner trim member 20 is attached to the outer trim member 18, the locking claw 50 of the locking piece 42 abuts (locks) to the peripheral portion of the locking hole 36. Here, in a state in which the locking claw 50 is locked to the peripheral portion of the locking hole 36, the length L1 of the straight line connecting the position of the distal end portion 48A of the locking piece main body 48 and the position of the root portion 48B. The length L2 of the locking piece main body 48 is set to be longer.

  For this reason, in a state where the locking claw 50 is locked to the peripheral portion of the locking hole 36, the locking piece 42 is elastically deformed. In other words, the locking claw 50 is locked to the peripheral portion of the locking hole 36 with the locking piece 42 being elastically deformed. That is, since the elastic force acts on the locking piece 42, the front end portion 50 </ b> A of the locking claw 50 is locked so as to bite into the peripheral portion of the locking hole 36. In this state, the contact surface 48 </ b> C on the vehicle interior side of the locking piece main body 48 is in contact (interference) with the inner edge portion of the locking hole 36. As described above, since the elastic force acts on the locking piece 42, the contact surface 48 </ b> C of the locking piece body 48 is in a so-called strong interference state with the inner edge portion of the locking hole 36. Yes.

  Thus, the outer trim member 18 (door trim 16) is in a state where the inner trim member 20 is attached to the outer trim member 18 via the locking piece 42 together with the mounting boss 40 (see FIG. 3). It can be attached to the door inner panel 24.

  As shown in FIG. 1, a circular mounting hole 52 is formed on the outer edge side of the door inner panel 24. On the other hand, as shown in FIG. 2, a pedestal 54 projects from the outer trim member 18. For example, a substantially conical clip 56 can be attached to the pedestal 54. The clip 56 is elastically deformable, and the clip 56 is attached to the periphery of the attachment hole 52 by press-fitting into the attachment hole 52. The door trim 16 is attached to the door inner panel 24 in a state where the clip 56 is attached to the periphery of the attachment hole 52 of the door inner panel 24. A locking hole 36 and a locking piece 42 are provided in the vicinity of the clip 56 and the base 54 (on the vehicle front side).

(Operation / effect of the door trim mounting structure for automobiles)
As shown in FIG. 1, the door trim 16 includes an outer trim member 18 and an inner trim member 20, and the inner trim member 20 is attached to the outer trim member 18. In the present embodiment, the upper frame 32B, the rear frame 32C, and the lower frame 32D of the mounting seat surface 32 provided at the periphery of the opening 28 formed in the outer trim member 18 are locked in addition to the insertion holes 34. A hole 36 is provided.

  Then, as shown in FIG. 4A, a locking piece 42 formed in the inner trim member 20 is inserted into the locking hole 36, and the locking piece 42 is elastically deformed and is locked. 50 is locked to the periphery of the locking hole 36. That is, a pressing force that presses the inner trim member 20 toward the outer trim member 18 side (outward in the vehicle width direction) acts via the locking piece 42. For this reason, a reaction force against the pressing force is generated in the inner trim member 20, and the inner trim member 20 can ensure a necessary rigidity in this portion.

  On the other hand, as shown in FIG. 3, the mounting boss 40 formed on the inner trim member 20 is inserted into the insertion hole 34, and the tip end portion of the mounting boss 40 is thermally crimped (the state where it is prevented from being detached). Thus, the inner trim member 20 is fixed to the outer trim member 18. In this state, a gap 38 provided between the inner trim member 20 and the outer trim member 18 is filled with the mounting boss 40. Thereby, the inner trim member 20 is firmly attached to the outer trim member 18 via the attachment boss 40. That is, the mounting boss 40 is stretched between the inner trim member 20 and the outer trim member 18, and the inner trim member 20 becomes difficult to bend.

  As described above, as shown in FIG. 4A, the locking piece 42 locked to the periphery of the locking hole 36 in an elastically deformed state, and the outer trim member as shown in FIG. Due to the mounting boss 40 fixed in a state where the door trim 16 is prevented from coming off, the rigidity of the door trim 16 during normal use is secured.

  Here, as shown in FIG. 4 (A), the locking piece 42 is elastically deformed so that the locking claw 50 is locked to the periphery of the locking hole 36, and the inner trim member It is not intended to stretch between 20 and the outer trim member 18. For this reason, when the inner trim member 20 is deformed to the outer trim member 18 side due to a secondary collision with the occupant's door trim 16 at the side collision of the automobile, as shown in FIG. The state in which the locking claw 50 is locked to the peripheral portion of the locking hole 36 is released (the locking claw 50 of the locking piece 42 is released from the peripheral portion of the locking hole 36).

  That is, the locking piece 42 moves in the locking hole 36 from the distal end portion 48A side of the locking piece main body 48 to the root portion 48B side. As described above, the locking claw 50 is locked to the peripheral portion of the locking hole 36 in a state where the locking piece 42 is elastically deformed, whereby a pressing force acts on the outer trim member 18 and the inner trim member 20 is pressed. Produces a reaction force against the pressing force. For this reason, when the latching claw 50 of the latching piece 42 comes off from the peripheral part of the latching hole 36, the reaction force generated by the latching piece 42 is reduced. That is, it is possible to reduce the collision reaction force due to the secondary collision of the occupant in the side collision, and to ensure the side collision performance related to the secondary collision of the occupant. Further, mounting bosses 40 are provided on the vehicle front side and the vehicle rear side of the locking piece 42 or on the vehicle upper side and the vehicle lower side of the locking piece 42, and the amount of rigidity reduced by the locking piece 42 is reduced. It is compensated by the rigidity of the mounting boss 40.

  From the above, according to the present embodiment, the rigidity of the door trim 16 can be ensured, and the collision reaction force due to the secondary collision of the occupant in the side collision can be reduced. In particular, in the present embodiment, since the locking hole 36 is provided at a height corresponding to the chest position and waist position of the occupant seated on the seat, in the height corresponding to the chest position and waist position of the occupant, The collision reaction force can be reduced. The locking hole 36 may be provided at a height corresponding to at least the chest position of the occupant.

  Further, in the present embodiment, as shown in FIG. 4A, in the state where the locking claw 50 is elastically deformed and locked to the peripheral portion of the locking hole 36, The contact surface 48 </ b> C is in contact (strong interference) with the inner edge of the locking hole 36. For this reason, as shown in FIGS. 4B and 4C, when the locking piece 42 moves from the distal end portion 48A side to the root portion 48B side in the locking hole 36, the locking piece 42 The contact surface 48C of the locking piece main body 48 moves while sliding on the inner edge of the locking hole 36. Thereby, sliding resistance arises between the locking piece 42 and the inner edge part of the locking hole 36, and, thereby, impact energy is absorbed. That is, the impact that the occupant receives from the inner trim member 20 at the time of a side collision can be reduced.

  Furthermore, in this embodiment, as shown in FIG. 4A, the locking piece 42 extends from the back side of the inner trim member 20 toward the vehicle width direction outer side and the vehicle rear side. That is, the locking piece main body 48 in the locking piece 42 is formed to be inclined with respect to a straight line along the vehicle width direction. As described above, due to the secondary collision of the occupant with the door trim 16 at the time of a side collision, as shown in FIG. 4 (B), the locking piece main body 48 moves inside the locking hole 36 due to the deformation of the inner trim member 20. Moving. The locking piece main body 48 is formed to be inclined with respect to the straight line along the vehicle width direction, so that the locking piece main body 48 is compared with the case where the locking piece main body 48 is formed along the straight line. 48 can be formed long. Thereby, the length which a sliding resistance produces between the locking piece main body 48 and the locking hole 36 can be lengthened. That is, the stroke in which the impact energy is absorbed can be lengthened.

  As shown in FIG. 4C, when the locking claw 50 of the locking piece 42 comes into contact with the door inner panel 24, the locking piece 42 is elastically deformed and the root portion (engagement) of the locking claw 50 is engaged. The front end 48 </ b> A) of the stopper main body 48 slides on the surface 24 </ b> A of the door inner panel 24. That is, the impact energy can be absorbed by the elastic force and sliding force of the locking piece 42.

  On the other hand, as shown in FIG. 2, a locking hole 36 and a locking piece 42 are provided in the vicinity of the base 54 and the clip 56 of the door trim 16. Since the clip 56 is attached to the peripheral portion of the mounting hole 52 by press fitting into the mounting hole 52 (see FIG. 1) formed in the door inner panel 24 (see FIG. 1), the clip 56 is attached to the door inner on the outer trim member 18 side. Rigidity that can withstand the pressing force for press-fitting into the panel 24 is required. For this reason, in the part in which the said base 54 and the clip 56 are provided, it sets so that rigidity may become larger previously than the other part in the outer side trim member 18. FIG. On the other hand, the portion where the locking piece 42 is provided is lower in rigidity than the portion where the mounting boss 40 is provided.

  Therefore, by providing the locking piece 42 in the vicinity of the base 54 and the clip 56, the mounting boss 40 is provided by the locking piece 42 at the mounting portion between the inner trim member 20 and the outer trim member 18. The rigidity lower than that of the portion can be secured by the rigidity of the pedestal 54 and the clip 56.

  In the present embodiment, the rotary side door 12 is illustrated and described, but the present invention may be applied to a slide type side door.

(Supplement of this embodiment)
In the present embodiment, as shown in FIG. 4A, the locking piece 42 extends from the back side of the front wall 20B of the inner trim member 20 toward the vehicle width direction outside and the vehicle rear side. That is, the locking piece 42 is formed integrally with the inner trim member 20, but may be formed separately from the inner trim member 20. Further, although the locking piece 42 is formed to be inclined with respect to a straight line along the vehicle width direction, it may be formed along a straight line along the vehicle width direction depending on the shape of the inner trim member 20 or the like. .

  Further, the locking piece 42 has a belt-like shape in which the tip portion is substantially V-shaped in a side view, but it is only necessary to be locked to the peripheral portion of the locking hole 36 in an elastically deformed state. It is not a thing. For example, although not shown, the locking claw may form a hook shape and bite into the peripheral portion of the locking hole 36. Alternatively, a saw tooth may be formed at the tip 50A of the locking claw 50 so as to bite into the peripheral portion of the locking hole 36. A pressing force that presses the inner trim member 20 toward the outer trim member 18 side acts via the locking piece 42, but a reaction force against the pressing force is generated in the inner trim member 20. In these modifications, this reaction force can be increased.

  Further, in the present embodiment, as shown in FIG. 3, the inner trim member 20 is fixed to the outer trim member 18 by heat caulking the tip of the mounting boss 40. Since it should just be attached to the outer side trim member 18, it is not restricted to this. For example, although not shown, a screw is screwed from the tip of the mounting boss, and the mounting boss is prevented from coming off by the head of the screw, so that the inner trim member 20 is fixed to the outer trim member 18. May be.

  In the present embodiment, as shown in FIG. 2, mounting bosses 40 are provided on the vehicle front side and the vehicle rear side of the locking piece 42 or on the vehicle upper side and the vehicle lower side of the locking piece 42. Since the mounting boss 40 is formed to ensure the rigidity of the inner trim member 20, at least one of the locking piece 42 on the vehicle front side and the vehicle rear side, or the locking piece 42 on the vehicle upper side. And it should just be provided in at least one of the vehicle lower side.

  Furthermore, in this embodiment, as shown in FIG. 4A, the contact surface 48C of the locking piece main body 48 is engaged with the locking claw 50 locked to the peripheral portion of the locking hole 36. Although set so as to abut (interfere) with the inner edge portion of the stop hole 36, the present invention is not limited to this. For example, the width dimension of the locking piece 42 and the width dimension of the locking hole 36 are formed to be substantially the same, and the locking piece 42 including the side surface of the locking piece main body 48 is the inner edge portion of the locking hole 36. May contact (interfere) with each other. Note that the locking piece main body 48 is not necessarily required to contact the inner edge of the locking hole 36.

  In the present embodiment, the pedestal 54 protrudes from the outer trim member 18 and the clip 56 is attached to the pedestal 54. However, the pedestal 54 is not necessarily required, and the clip 56 is attached to the outer trim member 18. May be provided integrally.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and other various modifications can be made without departing from the spirit of the present invention. It is.
